Description

Die Erfindung bezieht sich auf einen Hilfsrahmen für eine Radaufhängung eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1.The invention relates to a subframe for a wheel suspension of a motor vehicle according to the preamble of claim 1.

Aus der DE-OS 24 40 494 ist ein Tragrahmen für eine Radaufhängung eines Fahrzeugs bekannt, der am Fahrzeugaufbau befestigt ist und Lageraufnahmen für Radführungslenker umfasst. Dieser Tragrahmen besteht aus einem quer im Fahrzeug ausgerichteten Träger, der jeweils endseitig zwei Lenkerlager für eine Schräglenkerachse aufnimmt. Eine weitere Ausführung eines Hilfsrahmens für eine Radaufhängung (DE-A 25 36 060) besteht aus einem einteiligen U-förmigen Träger, der am Fahrzeugaufbau befestigt ist, wobei die Verbindung des Lenkerlagers zum Fahrzeugaufbau über eine gleiche Befestigungsschraube des Hilfsrahmens erfolgt.From DE-OS 24 40 494 a support frame for a wheel suspension of a vehicle is known, which is attached to the vehicle body and includes bearing mounts for wheel control handlebars. This support frame consists of a carrier aligned transversely in the vehicle, which receives two link bearings for a semi-trailing arm axle at each end. A further embodiment of a subframe for a wheel suspension (DE-A 25 36 060) consists of a one-piece U-shaped carrier which is fastened to the vehicle body, the connection of the handlebar bearing to the vehicle body being carried out using the same fastening screw of the subframe.

Aufgabe der Erfindung ist es, einen leichtgewichtigen Hilfsrahmen für eine Radaufhängung zu schaffen, der in einfacher Bauweise mit verringertem konstruktivem Aufwand ausgebildet ist.The object of the invention is to provide a lightweight subframe for a wheel suspension, which is designed in a simple design with reduced design effort.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved by the characterizing features of claim 1. The dependent claims contain further advantageous features.

Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, daß der Aufwand der Verbindungen zu den Lenkerlagern und dem zweigeteilten Hilfsrahmen herabgesetzt wird, da zusätzliche Verbindungen der beiden Teile des Hilfsrahmens entfallen. So wird in vorteilhafter Weise eine Befestigung eines ersten Querträgers an einem zweiten Querträger des Rahmens zur Aufnahme eines Lenkerlagers für einen Radführungslenker genutzt, wodurch zusätzliche schwergewichtige Lageraufnahmen am Hilfsrahmen entfallen können.The main advantages achieved by the invention are that the complexity of the connections to the link bearings and the two-part subframe is reduced, since additional connections of the two parts of the subframe are omitted. For example, an attachment of a first cross member to a second cross member of the frame is advantageously used to receive a link bearing for a wheel control arm, which means that additional heavy-duty bearing receptacles on the subframe can be omitted.

So wird zur Aufnahme des einen Lenkerlagers ein Spalt zwischen den beiden zu verbindenden Querträgern verwendet, um das Lager an seinen beiden Stirnseiten über parallele Tragflächen abzustützen. Der Spalt wird vorzugsweise zwischen einem vom Schenkel abgehenden Arm des einen Querträgers und einem Ansatz von einem weiteren Querträger gebildet, wobei der Arm gleichzeitig im Abstand zum Lager mit dem weiteren Querträger über eine Befestigungsschraube verbunden ist. Mit dieser Schraube ist ein weiteres Lenkerlager eines Radführungslenkers verbunden, das außenseitig des einen Querträgers angeordnet ist, wodurch der Aufwand einer zusätzlichen Befestigungsschraube neben einer Halteschraube für das Lager in vorteilhafter Weise vermieden wird.Thus, a gap between the two cross members to be connected is used to receive the one link bearing in order to support the bearing on its two end faces via parallel wings. The gap is preferably formed between an arm extending from the leg of one cross member and a shoulder of a further cross member, the arm being connected at a distance from the bearing to the further cross member via a fastening screw. With this screw, a further link bearing of a wheel control link is connected, which is arranged on the outside of a cross member, whereby the effort of an additional fastening screw in addition to a retaining screw for the bearing is advantageously avoided.

Mit dem einen Querträger ist ein Stabilisator-Lagerbock über zwei Befestigungsschrauben verbunden, wobei die eine Befestigungsschraube ein drittes Lenkerlager aufnimmt, das zwischen dem Querträger und einem Schenkel des Lagerbocks angeordnet ist. Dieser das Lenkerlager haltende Bolzen umfasst ein Exzenter-Einstellelement, mit dem der Nachlauf des Rades eingestellt wird.With the one cross member a stabilizer bracket is connected via two fastening screws, one fastening screw receiving a third link bearing, which is arranged between the cross member and one leg of the bracket. This bolt holding the handlebar bearing comprises an eccentric adjusting element with which the caster of the wheel is adjusted.

Der Hilfsrahmen 1 für eine Radaufhängung, insbesondere für eine Hinterradaufhängung in Mehrlenkerbauweise umfasst einen ersten vorderen Querträger 2, der mit einem zweiten hinteren Querträger 3 - in bezug auf die Fahrtrichtung F - zu einer Festigkeitseinheit verbunden und am Fahrzeugaufbau über mehrere Lager befestigt ist.The subframe 1 for a wheel suspension, in particular for a rear suspension in a multi-link construction, comprises a first front cross member 2, which is connected to a second rear cross member 3 - with respect to the direction of travel F - to form a strength unit and is fastened to the vehicle body via several bearings.

Am Hilfsrahmen 1 sind Lager 4 und 8 für einen unteren Querlenker 6 sowie ein Lager 5 für eine Spurstange 7 gehalten.Bearings 4 and 8 for a lower wishbone 6 and a bearing 5 for a tie rod 7 are held on the auxiliary frame 1.

Die obere Anbindung der Radaufhängung wird von zwei Lenkern 10 und 11 mit den Lagern 12 und 13 gebildet, wobei das Lager 12 am Hilfsrahmen 1 und das Lager 13 am Fahrzeugaufbau 14 vorgesehen ist.The upper connection of the wheel suspension is formed by two links 10 and 11 with the bearings 12 and 13, the bearing 12 being provided on the subframe 1 and the bearing 13 on the vehicle body 14.

Der vordere Querträger 2 ist U-förmig mit von einem querverlaufenden Tragteil 2a abgehenden Schenkeln 2b ausgebildet und erstreckt sich etwa in einer horizontalen Ebene X-X. Der hintere Querträger 3 weist endseitige Säulen 3a auf, die sich von einem querverlaufenden Tragteil 3b, das etwa in einer gleichen Ebene X-X mit dem vorderen Querträger 2 liegt, vertikal nach oben - in bezug auf die Ebene X-X - erstrecken.The front cross member 2 is U-shaped with legs 2b extending from a transverse support part 2a and extends approximately in a horizontal plane X-X. The rear cross member 3 has end pillars 3a which extend vertically upward from a transverse support member 3b, which is approximately in the same plane X-X with the front cross member 2, with respect to the plane X-X.

Die beiden Querträger 2 und 3 des Hilfsrahmens 1 sind über Befestigungsbolzen 16, 17 an jeder Seite miteinander verbunden, die auch gleichzeitig zur Befestigung der Lager 4 und 5 für die Lenker 6 und 7 dienen.The two cross members 2 and 3 of the subframe 1 are connected to each other via fastening bolts 16, 17, which also serve to fasten the bearings 4 and 5 for the handlebars 6 and 7 at the same time.

Das Lager 4 des Lenkers 6 ist in einem zwischen vom Schenkel 2b abgehenden Armen 2c des vorderen Querträgers 2 und dem hinteren Querträger 3 gebildeten Spalt 18 eingepasst und über den Bolzen 16 gehalten, der gleichzeitig die beiden Querträger 2 und 3 miteinander verbindet.The bearing 4 of the handlebar 6 is fitted in a gap 18 formed between the arms 2c of the front cross member 2 and the rear cross member 3 and is held by the bolt 16 which simultaneously connects the two cross members 2 and 3.

Der Spalt 18 zur Aufnahme des Lagers 4 wird von parallelen Flächen 21, 22 begrenzt, denen Stirnflächen des Lagers 4 entsprechend gegenüberstehen. Die durch den Bolzen 16 gebildete Schwenkachse verläuft unter einem stumpfen Winkel zum Schenkel 2b des ersten Querträgers 2.The gap 18 for receiving the bearing 4 is delimited by parallel surfaces 21, 22, which end faces of the bearing 4 face accordingly. The pivot axis formed by the bolt 16 extends at an obtuse angle to the leg 2b of the first cross member 2.

Gleichzeitig ist der Querträger 2 über den vom Schenkel 2b abgebogenen Arm 2c mit dem querverlaufenden Tragteil 3b des Querträgers 3 über den weiteren Bolzen 17 verbunden. Dieser trägt endseitig das Lager 5 für den Lenker 7, das außenanliegend des Tragteils 3b angeordnet ist. Der Bolzen 17 kann über ein mit dem Tragteil 3b verbundenen Schließblech 17a gehalten sein.At the same time, the cross member 2 is connected via the arm 2c bent by the leg 2b to the transverse support part 3b of the cross member 3 via the further bolt 17. At the end, this supports the bearing 5 for the handlebar 7, which is arranged on the outside of the support part 3b. The bolt 17 can be held via a striking plate 17a connected to the supporting part 3b.

Somit sind über die beiden Bolzen 16 und 17 jeder Seite des Hilfsrahmens 1 die Querträger 2 und 3 miteinander verbunden und gleichzeitig sind die Lager 4, 5 am Hilfsrahmen 1 festgesetzt.Thus, the cross beams 2 and 3 are connected to each other via the two bolts 16 and 17 on each side of the subframe 1 and at the same time the bearings 4, 5 are fixed on the subframe 1.

Wie Fig. 1 näher zeigt, ist mit der Säule 3a des Querträgers 3 ein Stabilisator-Lagerbock 25 mittels Befestigungsbolzen 26, 27 verbunden. Der Bolzen 27 trägt gleichzeitig das Lager 12 für den oberen Lenker 10, so daß eine separate Befestigung des Lagers 12 bzw. des Lagerbocks 25 entfällt.As shown in FIG. 1, a stabilizer bracket 25 is connected to the column 3a of the cross member 3 by means of fastening bolts 26, 27. The bolt 27 also carries the bearing 12 for the upper link 10, so that a separate attachment of the bearing 12 or the bearing block 25 is not necessary.

Nach einer weiteren Ausführung gemäß der Fig. 3 und 4 ist der Befestigungsbolzen 27 mit einem Exzenter-Einstellelement 28 versehen. Dies umfasst eine Exzenterscheibe 29 mit Sechskant 30, die drehfest mit der Schraube 27 verbunden ist, deren endseitiger Kopf von einer zweiten Exzenterscheibe 29a gebildet wird, die in einer Nut mit seitlichen Rampen angeorndet ist. Der Sechskant 30 kann um die Exzentrizität e1 zur Bolzenachse 34 versetzt sein, um die Exzenterscheibe 29 kleiner und somit leichter gestalten zu können. Eine Sicherung der Bolzenverbindung erfolgt über eine Befestigungsmutter 31. Zum Verstellen des Rades wird die Exzenterscheibe 29 über den Sechskant 30 zwischen Begrenzungen 32 und 33 des Lagerbocks 25 verdreht, so daß die Bolzenachse 34 eine Verlagerung und somit das Rad eine Verstellung erfährt. Diese Anordnung hat den Vorteil, daß Einstellung und Sicherung der Schraubverbindung von einer äußeren Seite her erfolgt, insbesondere wenn der Zugang zum endseitigen Kopf der Schraube 27 nicht möglich ist.According to a further embodiment according to FIGS. 3 and 4, the fastening bolt 27 is provided with an eccentric adjusting element 28. This comprises an eccentric disk 29 with a hexagon 30, which is connected in a rotationally fixed manner to the screw 27, the end-side head of which is formed by a second eccentric disk 29a, which is arranged in a groove with lateral ramps. The hexagon 30 can be offset by the eccentricity e1 from the pin axis 34 in order to make the eccentric disk 29 smaller and thus lighter. The bolt connection is secured by means of a fastening nut 31. To adjust the wheel, the eccentric disc 29 is rotated via the hexagon 30 between limits 32 and 33 of the bearing block 25, so that the bolt axis 34 is displaced and thus the wheel is displaced. This arrangement has the advantage that the screw connection is set and secured from an outer side, in particular if access to the end head of the screw 27 is not possible.
